The original Castlevania game had lots of hidden bags of treasure that would only appear if you squatted down on a certain block or stood still in a certain place for long enough. However, there's one treasure sack that can't be collected by any means. Why's it there? No idea.

First, make your way to what the game calls 'Stage 9', but what is actually the end boss of the third area. Find this block:

Now, just press Left for a few seconds and viola! A money bag that pops up in a completely inaccessible location.

Ultimately, this is kind of pointless, but you might be able to use it to win a bet or something.

Since we're talking about the original Super Mario Bros. lately, I've prepared a short video showing you where all the powerups are. Make sure you take real good notes because I kind of left out pesky things like 'context'.

Yeah, I know the sound gets out of wonk in a couple of places, but I'm too lazy to change it back, so you'll just have to consider those parts to be 'easter eggs'.

It might not seem like it now since so many of us have played it to death, but the original Super Mario Bros. is a tough game until you have the whole thing memorized, so if you're new to the game you're going to see this a lot:

But all is not lost! Once the title screen pops back up, hold down the A Button and press Start to start back up at the beginning of the world where you bought the farm.

Of course, as you get better, you probably won't need this any more. At least, that's the goal.
